Wow, that Rotella is shot from the fuel! Did you take the sample or someone else? I don't think that I have ever seen a Blackstone fuel % that high and my trips are 7 miles each way.

Was the car fully warmed up? Did you do some WOT runs before taking the sample? If you want to really get to the root of the problem, and want a more accurate fuel reading, you'll need to spend more than $30 on a uoa.

Yeah, I took at on my last oil change. The car was warmed up, I drove the to parts store to get the oil filter, and I took the sample in the middle of the drain. I didn't really do any WOT, but the car was warmed up, so I figured it was fine.

OP, I should add that I do far more short trips than I let on in those UOAs^^. I drive 6 miles to work and frequently go home at lunch. So that's 6 short trips per day, or more. The long highway trips on the weekends really help with fuel dilution, as others have mentioned. Though in your case it looks like your tuner needs to spend some time on fueling.

id sell the car and buy an old toyota or hunduha beater and forget the subaru.....that kind of useage???

yer just killing the car......slowly and painfully

what you are doing with the car is likely the WORST POSSIBLE THING you could do to it other than driving it straight into a wall at speed

Don't be stupid.

It's entirely possible (and probable) that the car needs fixing. It seems excessive that some short trips (I do more than just drive a few miles per day on it, like I said) would end up with DOUBLE the average fuel %.
